Section 8.1.3 says:
"A proxy server MUST NOT establish a persistent connection with an
HTTP/1.0 client".
Excerpt from section 19.7.1:
"An HTTP/1.1 server may also establish persistent connections with
HTTP/1.0 clients upon receipt of a Keep-Alive connection token."
Why is there difference in handling persistent connections for proxy
servers and for HTTP/1.1 servers?
Because it was recognized during the HTTP/1.1 design process that
the uncontrolled forwarding of HTTP/1.0 + Keep-Alive requests
through proxies (especially multiple levels of proxies) could lead
to confusing communication failures. See the first paragraph
of 19.7.1, which explains this.
19.7.1 should perhaps say "An HTTP/1.1 origin server" where
the part that you quoted says "An HTTP/1.1 server".
